MACHINE FOR BEVELING PHOTO-ENGRAVERS PLATES.

SPECIFICATION forming part of Letters Patent No. 708,436, dated September 2, 1902.

Application filed July 27, 1901- Serial No. 69,938. (No model.)

To all whom it may concern.-

Be it known that I, FERDINAND WEsEL, a citizen of the United States, residing in New York, in the borough of Brooklyn and State of New York, have invented certain new and useful Improvements in Machines for Beveling Photo-Engravers Plates, of which the fol lowing is a specification.

This invention relates to an improved machine for beveling photo-engravers plates in a very accurate and reliable manner by means of a power-driven mechanism; and the invention consists in the combination, in a beveling-machine, of a supporting-frame, a table on the same provided with longitudinal ways, a reciprocating slide-plate guided in said ways, a vertically-adjustable yoke-shaped support, a vertical web depending from said table, Ways provided in said web, said yokeshaped support having its inner arm guided in said ways of the web, a screw and handwheel on said web for adjusting said support, a clamping-screw for securing said support in adjusted position, a rotatable bevelingdisk mounted on said support; and the invention consists, further, in certain details of construction and combinations of parts, which will be fullydescribed hereinafter and finally pointed out in the claim.

In the accompanying drawings, Figure 1 represents a front elevation of my improved machine for beveling photo-engravers plates, parts being broken away and other parts in section to show the operative mechanism. Fig. 2 is a plan view of Fig. 1. Fig. 3 is a detail Vertical transverse section on line 3 3, Fig. 2. Fig. 4 is a side elevation taken from the right-hand side, and Fig. 5 is a side elevation taken from the left-hand side.

Similar letters of reference indicate corresponding parts. 7

Referring to the drawings, A represents the supporting-frame of my improved machine for beveling photo-engravers plates, and B is a table supported by the same. Approximately at the center of the table B, at one side of the same, is arranged a yoke-shaped support B, which is provided with bearings for the shaft 0 of a beveling-disk D, said disk being located at the inner end of the shaft 0 and provided at its circumference with a number of beveling-knives d. The knives cl are adjustable inwardly or outwardly from the periphery of the beveling-disk D, so as to provide for the proper setting of the same, and the knives are secured in such a manner that theycan be readily removed for the purpose of sharpening. Rotary motion is imparted to the shaft of the beveliug-disk D by a belt and pulley transmission from a drivingshaft S,supported in bearings at the lower part of the supporting-frame A, said driving-shaft beingprovided with afast and loose'pulley P P and with a suitable belt-shifting device L, operated by a hand-lever L, so as to start orstop the motion of the beveling-disk D, as required by the operator. The inner portion or leg B of the yoke shaped support B is extended in downward direction and guided in ways of an upright web A of the frame A, said leg being slotted and applied thereto by means of clamping-screws b b and adjusted higher or lower on the web A by a screw E, provided with a hand-wheel E at its lower end, as shown in Figs. 1 and 4. The purpose of the vertical adjustment of the yoke-shaped support is to provide for the beveling of printing-plates of various thicknesses, so that the setting of the beveling-knives according to the thickness of the various printing-plates which are to be beveled is not necessary by reason of the adjustment of the yoke-shaped support serving the same purpose, since by the adjustment of the latter the knives can be moved in proper relation to the plates to be beveled without their individual adjustment.

To the inner face of the yoke-shaped support B is attached a housing D, that extends around the beveling-disk D, said housing serving as a guard device for preventing injury to the operator.

The plate 1) to be beveled at the edge is placed on a slide-plate F, which is guided in suitable ways on the table B, said plate being firmly held in position on the slide-plate by means of a clamping bar M, which is guided at its ends in vertically-recessed posts m of the slide-plate. The clamping-bar M is applied to the plate 19 by means of eccentrics m, which are mounted on a longitudinal shaft m turning in bearings of the posts m, the shaft being provided at its front end with a handle m by which it is turned, so that the eccentrics are made to act on the vertically-guided clamping-bar M and clamp the plate firmly to the slide-plate F, as shown in Figs. 2 and 3.

To the front end of the slide-plate F nearest the operator is attached an upwardlyextending curved handle H, which serves for reciprocating the slide-plate F, so as to move the edge of the photo-engravers plate 19 past the knives of the beveling-disk D for producing the beveling of the edge of the same.

At the front end of the table is arranged a gage R, which is pivoted to a supportingplate 1, that is capable of adjustment in lateral direction, so that the edge of the gage can be accurately adjusted in line with the beveling-knives of the disk D for the proper adjustment of the plate to be beveled preparatory to subjecting its edge to the action of the beveling-disk. The supporting-plate is mounted slidably upon a dovetailed guidepiece r and may be locked thereto by a clampingscrew r and laterally adjusted thereon by a set-screw W, as shown in Figs. at and 5. The gage R is normally kept by a torsion-spring r, placed on its pivot-shaft, in raised position, but is lowered onto the table when the plate to be beveled is placed below the clamping-bar M and against the edge of the gage B. When this is accomplished, the plate is clamped by the bar M to the slideplate, the latter and the plate clamped thereto being then in position shown in dotted lines in plan View in Fig. 2. The operator then takes hold of the handle H and moves the plate from its forward position (shown in dotted lines into the position shown in full lines in Fig. 2) past the quickly-rotating beveling-disk. During the passage of the edge of the plate past the knives of the bevelingdisk the beveling of the edge of the same is accomplished in a quick, accurate, and

effective manner. The slide-plate is returned back to its former position, after which the plate to be beveled is released from the clamping-bar by turning the handle wa in the direction of the arrow shown in Fig. 3, after which the plate is turned so that the rear edge is placed against the edge of the lowered gage R, clamped again to the slide-plate, and then moved backward with the same past the beveling-disk D, so that the next edge is beveled. This operation is repeated until all the edges of the photo-engravers plate are beveled. The slide-plate F is arrested in its backward motion by a stationary stop f at the end of the table B, as shown in Fig. 4, while a guard-plate h, near the handle H, serves as a protection for the hand of the operator.

Having thus described my invention, I claim as new and desire to secure by Letters Patent In a machine for beveling photo-engravers plates, the combination, of a supportingframe, a table on the same provided with longitudinal ways, a reciprocating slide-plate guided in said ways, a vertically-adjustable yoke-shaped support, a vertical web depending from said table, ways provided in said web, the inner arm of said support being guided in the ways of said web, a screw and hand-wheel on said web for adjusting said support, a clamping-screw for securing said support in adjusted position, and a rotatable beveling-disk mounted on said support, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

FERDINAND WESEL.
